A headset that talks visually impaired people around cities has been designed by Microsoft. It works with a Windows phone and uses location and navigation data with a network of information beacons in urban locations to describe routes.
The headset was tested on a journey from Reading to London, including shopping, bus and train travel.
The charity Guide Dogs, which helped develop the technology, said it could help improve lives for visually impaired people.
The headset is an adapted version of one already on the market. Designed for cyclists, it sits in front of the ear so as not to drown out traffic and environmental noise.
Sound is conducted through the jawbone and the headset gives a series of verbal and non-verbal descriptions.
